Is itchiness normal one month post-op? Septorhino

I actually had septorhinoplasty and alar flar reduction around a month ago. I've noticed that I feel itchiness on the OUTSIDE of the nose. At least it feels like the outside. Around the nostril area, maybe also alar incisions, and even the tip sometimes. Is that more to do with the skin than the surgery? Also is it normal at this point to have slight pain along the bridge when touching it?
